Originally grounded in library and information science, the majority of information behaviour and information seeking theories focus on task-based scenarios where users try to resolve information needs. While other theories exist, such as how people unexpectedly encounter information for example, they are typically related back to tasks, motivated by work(More)
In trying to understand Exploratory Search, the community has focused on users who are working towards an information need, but who are unclear of their goal, technology, or domain of information.
